问题 I have existing code in c and c++. I have added these c files and cpp files in Android.mk file. And I have successfully created the .so files named itv.so in my application. But now when I am trying to run Android application It is showing error like... 12-20 13:26:31.362: E/AndroidRuntime(716): FATAL EXCEPTION: main 12-20 13:26:31.362: E/AndroidRuntime(716): java.lang.ExceptionInInitializerError 12-20 13:26:31.362: E/AndroidRuntime(716): at com.example.Internet_TV12.onCreate(Internet_TV12

问题 I want to use android NDK in my project. So my question is, how to integrate and execute default sample project of hello-jni from android NDK ? Please provide me step by step solution on it ... I don't know anything about it... 回答1: 1. First Create Android Project 2. Then Create Folder in the Project with name jni (Dont use other name) 3. Create File With the Android.mk ( Rightclick on the jni folder ->New -> File - >Android.mk) // Coding To Build Path and Access LOCAL_PATH :=$(call my-dir) /

问题 In my new project, I need to base on a c written project. And I know that I can use the NDK to do it, but here is a question: how to rewrite the standard Makefile into the Android.mk ? And further more, in Android, can I, neglecting the ndk, build the project directly using the jni to adapt the c project into the android project? And anymore idea to adapt the c project into the android project? thx. At last, here is the Makefile: # Makefile.in generated by automake 1.10.1 from Makefile.am. #

问题 I've read the similar questions, but the one that answers mine applies only to VisualStudio. I am using Eclipse and developing an Android application using Cocos2d-X, which is a framework that uses Android's NDK. I created a class named Config, which contains all of the application's constants such as ball sizes and fps. Below is how I arranged the code. Config.h #ifndef __CONFIG_H_ // this was auto-generated by eclipse #define __CONFIG_H_ class Config { public: static const double GRAVITY;

问题 I want to user my c++ code in a android/opencv/ndk project. When I paste the files into the jni folder and open them, the compiler gives me invalid argument errors for functions like substr or fwrite. An example: #include <string> #include <vector> using namespace std; using namespace cv; ... std::string str="We think in generalities, but we live in details."; std::string str2 = str.substr (12,12); does the compiler quit for substr with: Invalid arguments ' Candidates are: std::basic_string

问题 I am working on including a shared object file onto the Android OS image through the NDK project. The android.mk file looks like this LOCAL_PATH := $(call my-dir) include $(CLEAR_VARS) LOCAL_MODULE := Myaccessories LOCAL_SRC_FILES := libMyaccessories.so include $(PREBUILT_SHARED_LIBRARY) And I have added the "libMyaccessories.so" to the jni folder where the android.mk is located. On ndk-built, it results in error which is as below Prebuilt : libMyaccessories.so <= jni/ Install :
